Am I hardwired or not?

Ring Video Doorbell (2nd Gen). I've installed this with a wired connection to the previous doorbell power supply. The voltage measures 13.5v at the connecting screws on the back of the doorbell. Device Health on my dashboard reports the power source as battery, not hardwired. However, the mobile app shows the battery symbol with a lightning strike in it. The battery percentage has not increased by even 1% in the 5+ hours since the the hardwiring connection was made. Am I hardwired or not?
